VF-8A Triple-Offset

SHAFT STRENGTH UPGRADED
Shaft strength increased by splined shaft without drilling on the shaft for taper pin.

BLOW-OUT PROTECTION
Both the shaft stop and bottom cover offers reliable blowout protection.

DISC
Pin-less design provides easily maintenance work.

BI-DIRECTIONAL SHUTOFF DESIGN
The floating sealing design is self-adjustable and the sealing surfaces of an elliptical sealing system are completely in contact at the final position only. This mechanism provides flawless bubble tight shutoff.

For flanged end valve, the shaft is positioned at the flange side which reduced the possibility of external leakage caused by the ambient temperature changed.
